To all whom it may concern:

Be it known that l, .lTlENRY J. Lnwnnzvcn, c1tizen of the United States, residing at Long beach in the count 7 of Los jin 'eles and 7 l a State of Cahi'ornia, have invented eertam new and useful improvements in Wave or Tide Motors, 01' which the following is a specification.

The present invention relates to certain new and useful improvements in the construction of that type of hvdraulic motors which are particularly designed for operation by wave power, and aims to provide a motor which will utilize the back How or current of the under-tow as well the initial power of the waves.

To this end the invention resides principally in the provision oi a motor mechanism comprising a plurality of niovablelloats or buckets, the said motor mechanism being mounted within a peculiarly constructed casing which causes the initial i'orce of the waves to act upon the floats when moving in one direction and the under-tow to act upon the buckets when moving in the opposite direction. i

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of co istruction and the means 101' e'llecting the result, reference is to be had to the following description and accompanying drawings, in which:

Figure l is a longitudinal sectional view through the wave motor. Fig. 2 is a trans verse sectional view through the same. i i 3 is a horizontal sectional view. Fig.4 is a detail view of one of the floats and the chain links to which the same is attached.

Corresponding and like parts are ra er-red to in the following description and indicated in all the views of the orawing's by the same reference characters.

The motor mechanism proper is inountci within a peculiarly designed casim comprising the spaced sides having their lower portions connected by a pair of transverse walls 2-2, the space between which constitutes a ballast chamber and is adapted to be filled with sand or lilre lnaterial l'or the pur pose of anchoring the motor in a suitable position upon the bed of the ocean or water-w ay from which the power is to be derived. A transverse and horizontally disposed partition 3 is supported by the sides 1 toward the upper portions thereof, guide members against those floats 9 under located at opposite longitudinal edges oi the partition A pair of shaft-s 5 are iournaled between the opposite end portions of the guide members 4:, one of thesaid shai'ts est-ending tin-(nigh the casing and havthe drive wheel '2' keyed thereon. u The esponding pulleys or sprockets 5 upon t to two shafts 5 are connected. by bolts which are in the not e oi the sprocket chains 8. Buckets or floats -9 are carried by these chains 8 at intervals, the said buckets moving forwardly upon one side of the horizontal partition 3 and rearwardly upon the opposite side oi the said horizontal part'tion.

in the sueciiic construction oi the floats 9 it will observed that the same comprise the spaced side pieces 10 liavug the cross pieces ll interposed between the extremities thereof. Attention also directed tothc lactchat the pivot pins 112 of the chain links to which the iloals 9 are attached are extended upon both sides of the chain, one set oi extensions entering the onus of the floats while the opposite set are connected by the 'liiil; ineniborslg and have the rollers 14 journaled thereon. These rollers 1+3- are designcd to engage the upper edge of the guide members 4 and prevent any binding of the floats ll the latter are traveling over the upper face of the horizontal. partition 3.

Ledges 15 carried by the sides 1 ofthc casing above the ballast chamber, the said ledges being located. below the horizontal partition 3 so as to enga the rollers l4. and

prevent sagging or binding of the floats 9 when traveling under the partition 3.

. i A 1 1 One end oi the casing 15 closed o an upwardly inclined wall 15 which extends slightly above the sides l, the said wall serving to retard the waves and to cause the me to fell upon the illoats 9 thereby causing those floats over the horizon partition 3 to 1110 e forwardly. The opposite end of the a .n is formed a mouth 17, the lat- Haring; sides of which operate to direct the )(lCli flow of the water or the under tow the horizontal partition 3, thereby causing the said floats to travel rearwardly. Suitable outlet ports 18 are formed in the sides 1 of the casing and serve as an exit for the back flow after having acted upon the heats 9.

Having thus described the invention, what is claimed as new is;

l. in a hydraulic motor, the combination of a casing chamber, and a motor mechanism mounted upon the casing.

2. In a hydraulic motor, the combination provided with aballast receiving opposite edges of the transverse partition,

shafts j ournaled between the guides, sprockets fast upon the shafts, endless belts connecting the sprockets, floats carried by the of a casing provided with a ballast receiving 1 endless belts and moving in opposite direc chamber, endless belts mounted within the tions upon opposite sides of the transverse casing, floats carried by the endless belts, partition, rollers carried by the endless belts and means for directing the water against I for engaging the guide members, and means the floats.

3. In a hydraulic motor, the combination of a casing having an upwardly inclined wall at one end thereof and a mouth at the oppoof a casing, a site end, endlessbelts mounted within the l by the casing,

casing, and floats carried by the endless belts, the said inclined wall directing the water against the floats when moving in one direction while the water entering through the before mentioned mouth acts upon the I bands, and

for directing the water against the floats upon opposite sides of the transverse partition.

7. In a hydraulic motor, the combination transverse partition supported a guide member at each side of the partition, a ledge supported by each side of the casing, shafts mounted within the casing, pulleys upon the shafts, bands con-.

pulleys, buckets carried by the necting the rollers also carried by the bands,

floats when moving in an opposite directionj I the said rollers engaging the guide members 4. In a hydraulic motor, the combination I of a casing comprising sides connected by a verse transverse partition, the said casing havingan upwardly inclined wall at one end thereof and a mouth at the opposite end, endless belts mounted within the casing, floats carried by the endless belts and moving in opposite directions upon opposite sides of the transverse partition, the before mentioned inclined walls serving to direct the water against the floats upon one side of the partition while the water entering through the before mentioned mouth acts upon the floats upon the opposite side of the partition.

6. In a hydraulic motor, the combination of a casing comprising sides connected by a transverse partition, guides mounted at when traveling upon one side of the transpartition and the before mentioned led es when traveling upon the opposite side f tie transverse partitlon.

8. In a hydraulic motor, the combination of a casing having a mouth at one end thereof and an inclined wall at the opposite end, a transverse partitipn supported within the casing, and a motor mechanism mounted within the casing and comprising floats moving in one direction upon one side of the transverse partition and in the opposite direction upon the opposite side of the transverse partition, the inclined end of the casing directing the initial force of the Waves against the floats moving in one direction while the mouth directs the back flow against the floats moving in the opposite direction.

In testimony whereof I allix my signature in presence of two witnesses.
